Which are the best graphics cards?

AMD’s Radeon R9 270 graphics card reviewed

AMD’s Radeon R9 series is growing at an alarming rate. Just over a month ago, we were treated to the R9 280X and R9 270X. AMD followed up with the top-of-the-line R9 290X in late October and the slightly less top-of-the-line (yet much more compelling) R9 290 last week.

Today, AMD pulls back the curtain on the R9 270, which extends the R9 family down to the $179 price point. This is the family’s most affordable member, and it’s also the least power-hungry. It gets by with a single six-pin PCI Express power connector with a “typical board power” of only 150W, by AMD’s count.

The R9 270 will face off against Nvidia’s fastest sub-$200 card, the GeForce GTX 660. Nvidia slashed the GTX 660’s price to $179 last month, although today, a Newegg search shows the card selling for $190 before mail-in rebates. AMD, then, has an opportunity to undercut Nvidia with a newer product. But will the R9 270 be better?

Pitcairn’s latest gig

The Radeon R9 270 is based on the same Pitcairn chip as the 270X and the older Radeon HD 7800 series. As you can see in the table below, the R9 270 features a fully enabled version of the chip, just like the R9 270X and the older Radeon HD 7870.

Radeon HD 7850 2GB 860 1024 55 28 4. 8 GT/s 256

Radeon R9 270X ?? 1050 1280 80 32 5.6 GT/s 256

In fact, as far as I can tell, the R9 270 only differs from the R9 270X in its GPU clock speed and power envelope. The R9 270 runs about 75MHz slower (though its memory is clocked at the same 5.6 GT/s), and AMD has cut typical power consumption from 180W to 150W. The trimmed power envelope allows for this:

The R9 270 only requires a single six-pin PCI Express power connector, which is good news if you’re stuck with a lower-wattage power supply. The R9 270X and Radeon HD 7870 both need two six-pin connectors, while the GTX 660 requires only one. So far, then, Nvidia has had a small flexibility advantage on that front.

GeForce GTX 660 25 83 2. 0 3.1 144

Based on our theoretical numbers, the drop in clock speed doesn’t put the R9 270 at much of a disadvantage versus to the R9 270X. The Asus version of the R9 270 that AMD sent us actually runs at 975MHz instead of the reference 925MHz, which helps narrow the gap even more.

Compared to the GTX 660, the R9 270 has, on paper, a higher pixel fill rate, a similar texture filtering rate, higher shader throughput, and much more memory bandwidth. Its only disadvantage is a rasterization rate about two thirds that of the GTX 660.

The R9 270 has another perk worth mentioning: it comes with a free copy of Battlefield 4. Or, at least, some versions of it do. Or, they’re supposed to.

Yeah, this card’s game bundling situation is clear as mud right now. AMD originally said that all R9-series cards would ship with BF4, but it now tells us that it will be up to retailers and vendors to decide which of their cards ship with the game. As of November 14, we can’t find a single R9 270 in stock at Newegg with BF4 included.

The GeForce GTX 660, by contrast, ships with Assassin’s Creed IV: Black Flag and Splinter Cell Blacklist, plus a $50 discount on the purchase of an Nvidia Shield handheld console. This deal applies to all GTX 660s listed at Newegg. I don’t know a lot folks interested in buying a Shield, and I expect serious PC gamers to log far more hours in Battlefield 4 than in the titles Nvidia offers. Still, an actual game bundle beats the promise of one.

But I digress. We’ve still got a whole suite of game benchmarks to show you—after a brief detour through our testing methods.

Our testing methods

We tested using our tried-and-true “inside the second” methods. Since we don’t have FCAT equipment up here at TR North, we used Fraps to generate all our performance numbers.

Fraps gives us information about things happening at the start of the rendering pipeline—not, as FCAT does, at the end of the pipeline, when frames reach the display. Having both sets of numbers would be better, but the Fraps data is largely sufficient for the kind of testing we’re doing here. We don’t expect there to be much of a discrepancy between Fraps and FCAT numbers on single-GPU, single-monitor configurations like these.

This time, we’ve run most of our Fraps numbers through a three-frame low-pass filter. This filter is designed to compensate for one of the side effects of triple buffering. It should smooth out irregularities in our frame time measurements that don’t actually affect when the frames are shown on the display. We didn’t apply the filter to our BioShock Infinite numbers, since that game is based on the Unreal Engine. Most UE games don’t use triple buffering, so the filter isn’t appropriate for them.

Whether filtered or not, our “inside the second” Fraps numbers are far more informative than the raw frames-per-second data produced by more conventional benchmarking techniques. Such data can cover up problems like latency spikes and micro-stuttering, which have a real, palpable impact on gameplay.

For more information about Fraps, FCAT, and our inside-the-second methodology, be sure to read Scott’s articles on the subject: Inside the second: A new look at game benchmarking and Inside the second with Nvidia’s frame capture tools.

As ever, we did our best to deliver clean benchmark numbers. Tests were run at least three times, and we reported the median results. Our test systems were configured like so:

Thanks to AMD, Corsair, Crucial, and Kingston for helping to outfit our test rig. AMD, Asus, Nvidia, and XFX have our gratitude, as well, for supplying the various graphics cards we tested.

Image quality settings for the graphics cards were left at the control panel defaults, except on the Radeon cards, where surface format optimizations were disabled and the tessellation mode was set to “use application settings.” Vertical refresh sync (vsync) was disabled for all tests.

We used the following test applications:

  • Battlefield 4
  • BioShock Infinite
  • Crysis 3
  • Far Cry 3
  • Tomb Raider
  • Fraps 3.5.9
  • GPU-Z 0.7.3

Some further notes on our methods:

  • We used the Fraps utility to record frame rates while playing 60- or 90-second sequences from the game. Although capturing frame rates while playing isn’t precisely repeatable, we tried to make each run as similar as possible to all of the others. We tested each Fraps sequence three times per video card in order to compensate for variability. We’ve included frame-by-frame results from Fraps for each game, and in those plots, you’re seeing the results from a single, representative pass through the test sequence.
  • We measured total system power consumption at the wall socket using a P3 Kill A Watt digital power meter. The monitor was plugged into a separate outlet, so its power draw was not part of our measurement. The cards were plugged into a motherboard on an open test bench.

    The idle measurements were taken at the Windows desktop with the Aero theme enabled. The cards were tested under load running Crysis 3 at the same quality settings used for our performance testing.

  • We measured noise levels on our test system, sitting on an open test bench, using a TES-52 digital sound level meter. The meter was held approximately 8″ from the test system at a height even with the top of the video card.

    You can think of these noise level measurements much like our system power consumption tests, because the entire systems’ noise levels were measured. Of course, noise levels will vary greatly in the real world along with the acoustic properties of the PC enclosure used, whether the enclosure provides adequate cooling to avoid a card’s highest fan speeds, placement of the enclosure in the room, and a whole range of other variables. These results should give a reasonably good picture of comparative fan noise, though.

  • We used GPU-Z to log GPU temperatures during our load testing.

The tests and methods we employ are generally publicly available and reproducible. If you have questions about our methods, hit our forums to talk with us about them.

Battlefield 4

Testing multiplayer games involves a lot of finicky variability, so I stuck with Battlefield 4‘s single-player campaign. Benchmarking was done at the start of the Singapore beach landing, which features cataclysmic environmental effects as well as explosions, gunfire, and… well, see for yourself:

Testing was conducted at 1080p using the game’s built-in “Ultra” detail preset.

The R9 270 earns itself another gold medal in BioShock Infinite—though here, it’s so close to the 7870 that there’s hardly any difference between the two.

Nvidia, meanwhile, is at a disadvantage again. The GTX 660 distances itself nicely from the 7850 2GB this time, but it’s still a ways behind the R9 270 and the 7870. The GTX 660 also spends a little more time than the Radeons above our 33-ms frame time threshold, but not much. We’re talking about 35 ms out of a 60-second run here, a nearly negligible span of time.

Tomb Raider

Developed by Crystal Dynamics, this reboot of the famous franchise features a young Lara Croft. I tested it by running around a small mountain village near the beginning of the single-player campaign.

Here, too, I went with the “Ultra” detail preset at 1080p. In Tomb Raider, that preset enables tessellation effects and a whole host of other goodies.

I think some kind of pattern is emerging here. Yet again, the R9 270 edges out the 7870 to snag the gold medal—and yet again, the GTX 660 doesn’t quite measure up.

Crysis 3

There’s not much to say about Crysis 3, except that it’s the latest Crysis game, and it has truly spectacular graphics. To benchmark it, we ran from weapon cache to weapon cache at the beginning of the Welcome to the Jungle level for 60 seconds per run.

Testing was done at 1080p using the medium detail preset with “very high” textures and medium SMAA antialiasing. I thought these cards would be able to handle the “high” preset, but the game just didn’t feel smooth at that setting.

So, this is interesting. With all the cards, the upper 5% of frame times are much higher than the rest. Our 99th percentile results reflect this, with all the cards neck and neck around 31-32 ms. That means the last 1% of frames are rendered at the equivalent of 31-32 FPS or less. We’re not seeing a lot of particularly large spikes in frame rendering times, as evidenced by our beyond-a-threshold data, but the game definitely feels less smooth than those FPS averages suggest. Why? Quite likely because of the constant variance from relatively low frame rendering times of around 10 ms to relatively high frame times around 35 ms. This problem may be caused by the difficult workload in this section of the game. There’s a tremendous amount of geometry detail in the grass here.

Oh, and if you’re wondering which card wins here: excluding the R7 260X, which clearly spends more time above 20 ms than the rest, it’s kind of a toss-up—at least in this particular part of Crysis 3.

Far Cry 3
Far Cry 3 Blood Dragon is a little too technicolor for my taste, so I tested Far Cry 3, which is based on the same engine. I picked one of the first assassination missions, shortly after the dramatic intro sequence and the oddly sudden transition from on-rails action shooter to open-world RPG with guns.

The game was run at 1080p using the “Ultra” detail preset. HBAO was enabled, as well, but MSAA was left disabled.

A-ha! Finally, the GeForce GTX 660 scores a victory, albeit a small one. The Nvidia card is on par with the R9 270 and 7870 in Far Cry 3 in terms of the frame rate average and in our latency-focused “time spent beyond X” metrics, which attempt to quantify the “badness” or lack of smoothness in each card’s performance. However, the GTX 660’s 99th percentile frame time is slightly lower. A look at the full frame latency curve shows that the GTX 660’s frame times don’t rise quite as much after the 95th percentile mark compared to the Radeons. In other words, with the toughest frames to render, when animation smoothness is most threatened, the GTX 660 performs best.

Given how the R9 270 performs in our other games, though, this showing isn’t quite enough to vindicate the GTX 660. The R9 really is just about as good in this game.

Power consumption

For some reason, the R9 270 draws more at idle than our 7870 card—an XFX Black Edition model underclocked to match reference specs. The R9 270 is more power-efficient under load, however, and it’s about the same when the display is switched off. As we saw on the previous pages, that reduced power consumption under load doesn’t coincide with reduced performance; on the contrary, the R9 270 generally matches or beats the 7870.

Noise levels and GPU temperatures

Save for the R7 260X, all of these cards have nice and quiet dual-fan coolers. Their noise levels are pretty much on par with one another—not just according to our decibel meter, but subjectively, as well.

The R9 270 draws less power than the 7870 under load, and it’s outfitted with a nice Asus DirectCU II cooler. No wonder it runs so cool.

Conclusions

We’ll once again wrap things up with a couple of value scatter plots. In both plots, the performance numbers are geometric means of data points from all the games we tested. The first plot shows 99th-percentile frame times converted into FPS for easier reading; the second plot shows simple FPS averages. Prices were fetched from Newegg, the GPU vendors, and the card makers, depending on what was appropriate.

The best deals should reside near the top left of each plot, where performance is high and pricing is low. Conversely, the least desirable offerings should be near the bottom right.

Well, I think this is pretty clear-cut. The Radeon R9 270 outperforms the GeForce GTX 660 overall, and it does so while drawing roughly the same amount of power at idle and under load—and while sipping fewer watts at idle with the display powered off.

The Asus version of the R9 270 we tested may be hot-clocked, but it’s priced at the same $179.99 as other R9 270 cards. That makes it arguably a better choice than the GTX 660, which starts at $189.99.

That is, as long as you don’t start accounting for game bundles.

All GTX 660s listed at Newegg come with Assassin’s Creed IV: Black Flag and Splinter Cell Blacklist plus a $50 Shield discount. AMD says some R9 270s are supposed to ship with Battlefield 4, but we can’t find any such bundles at Newegg right now. If freebies matter more to you than a little extra performance, then the GTX 660 may be the card for you. But if you somehow manage to score an R9 270 with a free copy of BF4, then I’d say that’s the better bargain—simply because Battlefield multiplayer should have much more replay value than the titles Nvidia offers.

The R9 270 has another thing going for it: Mantle. Many Mantle-enabled games are on the way, and the performance gains hinted at by developers sound tantalizing. It could be that the R9 270’s lead over the GTX 660 will grow significantly thanks to the new API. That’s another thing to consider.

As for the R9 270’s big brother, the R9 270X, well… folks with (slightly) deeper pockets may prefer to cough up the extra $20 for it, but given the small difference in clock rates between the two, I’m not sure I’d bother.

Review: Sapphire AMD Radeon R9 270 graphics card — Graphics

There’s been a deluge of graphics card announcements of late, happily coinciding with the holiday season that begins with the release of hotly-anticipated games. Sure, we’d all love a GeForce GTX 780 Ti or Radeon R9 290X, but the solemn truth is that both are way over budget for most people.

And given that many readers use 1,920×1,080-pixel resolution monitors affording a full-HD experience, looking for the card with the most attractive bang-for-buck is arguably more important than salivating after the very best silicon.

So you want to play the newest games on that inexpensive, 22-24in monitor but don’t want to fork out a king’s ransom to do so, right? Nvidia has the GeForce GTX 760 (£175) and GTX 660 (£140) GPUs for this purpose, and AMD counters with the R9 270X (£150) GPU launched last month, which is basically a Radeon HD 7870 with faster clocks.

AMD believes the Pitcairn architecture, first debuted in March 2012, has enough going for it to be the foundation for yet another GPU. Let’s now welcome the Radeon R9 270 2GB into the mid-range fold by looking at its vital statistics.

Architecture analysis — R9 270

The Radeon R9 270 (non-X) shares the same architecture as the R9 270X and Radeon HD 7870. It differs by being clocked in at a lower core frequency, humming along at a peak speed of 925MHz, This means it has around 12 per cent less shading power, but retains the same backend, encompassing a 256-bit memory bus and GDDR5 RAM rated at an effective 5,600MHz.

Crunch the numbers and the R9 270 is destined to be between 5-10 per cent slower than its bigger brother. In fact, it’s a very good match for the outgoing HD 7870, which beats it in shading prowess but loses out with respect to memory bandwidth. We’re happy to see that, unlike the Radeon HD 7850, AMD hasn’t reduced the core count on the cheaper card. Not wanting to step on the silicon shoes of the R9 270X, AMD’s partners have limited scope to increase the core speed, because an R9 270 card running at 1,050/5,600MHz becomes a de facto 270X.

Having less core muscle has the added benefit of AMD specifying the R9 270 with a 150W TDP, or, more pragmatically, a single 6-pin power connector. This, then, is a GPU designed to offer solid 1080p gaming performance at the most attractive price. The cheapest boards are likely to appear at retail for $179 (£135) rising to $199 ($150) and therefore filling the gap vacated by the outgoing Radeon HD 7870.

Summary

The Radeon R9 270 2GB card is architecturally very similar to the Radeon HD 7870 that’s been doing the rounds for the past 18 months.
There is no manifestly new technology here; rather, AMD is using price as the motivating factor for purchase. With that in mind, let’s take a look at an overclocked card from Sapphire.

When we got our first look at the Radeon HD 7870, our review sample used AMD’s reference cooler. Once the card made its way to retail, most board partners opted to use custom coolers and factory overclocks to differentiate themselves, rather than stick to the tried and tested AMD blueprint. HIS’s take on the card has been to use the reference PCB and add its venerable IceQ GPU cooler. The 7870 IceQ is also overclocked out of the box and, thanks to AMD’s recent price cut, only £10 more expensive than the reference card.

Click to enlarge — the large cooler means the card occupies three expansion slots

The IceQ cooler uses a radial fan design, where the rear-mounted cooling fan pushes air towards the front of the card and out via the rear I/O slot. As the fan assembly is raised away from the PCB, HIS has used a larger fan that can pull air from above as well as below the card, but the large fan shroud essentially makes this a triple-slot card. HIS says the triple-slot design is beneficial for crossfire setups, as the extra space leaves more room for cooling, but you’ll need a motherboard with three PCI-E x16 slots to accommodate them. At 285mm in length, the 7870 IceQ is also longer than the standard card, meaning you’ll struggle to fit it into a smaller case. Make sure you measure the available space before you buy, as this is a seriously big card, despite its mid-range GPU.

With such a large cooler, HIS has added a metal support strut along the top edge to add rigidity to the card. This is fairly standard practice amongst third party cooler designs, but we could still spot a little bend towards the end of the cooler when fitted into our test system – that cooler is certainly heavy, and only attached by four screws around the GPU core.

The cooler uses four nickel-plated copper heatpipes which run through a large aluminium heatsink from a copper baseplate. The memory modules are actively cooled using thermal pads fitted to an aluminium contact plate that surrounds the core copper contact plate.

Unbolting the gigantic cooler from the PCB reveals that the board itself is fairly small at 241mm in length – it’s just the heatsink and accompanying shroud that adds to its size and weight. Powered by two six-pin PCI-E power connectors, and with one HDMI, one DVI and two mini DisplayPort outputs, HIS hasn’t deviated far from the reference layout.

All the power circuitry, as well as the five GPU power phases, has been shifted to the front of the PCB, well away from the heatsink fan. The two memory phases are at the other end of the card, with the GPU core positioned right in the middle. Without direct, the power phases may run hotter than on a card with a different layout, but they still benefit from airflow over them and considering how energy efficient the HD 7870 is, it isn’t a major issue.

Shipping with a 1100MHz core and 2GB of 4.8GHz GDDR5 memory, HIS has chosen to overclock the GPU core by 10 per cent but leave the memory at its reference frequency. Voltages have also been left at the stock 1.219v.

As it’s essentially the same as AMD’s reference card, you of course get all the features we’ve come to expect from the Big Red, including Eyefinity support for up to six displays (even if there are only four outputs on the card itself), PCI-E 3.0 and Crossfire, although with only one connector you’re limited to a two-card setup.

New GPUs: what kind of islands are these?

When discussing the daring initiatives of the “reds”, it is easy to forget about the R-series video cards themselves, three of which are the Radeon R7 260X, R9270X and R9 280X are already available for testing. And the first question in connection with the newcomers is this: are these the long-awaited GPUs of the Volcanic Islands family? In fact, everything turns out to be pretty confusing. The fact is that AMD has not officially announced the names of the chips that formed the basis of the trinity that arrived for the tests. But according to some indirect signs (marking on the boards) and information from third parties, it can be judged that the GPUs are called, in ascending order of performance, Bonaire XTX, Curacao XT, Tahiti XTL. Everything is clear about the first and third ones: these are updated versions of the chips of the same name belonging to the Sea Islands and Southern Islands families, respectively, but Curacao XT, which does not differ from Pitcairn XT in its main features, how did it deserve a new name?

Regardless of the formal classification, it is easier to consider the new «gems» as new revisions of what we have already seen in the Radeon HD 7000 line. Moreover, Bonaire XTX was more fortunate than others in that it acquired a TrueAudio unit and an updated PowerTune controller, while Curacao XT and Tahiti XTL do not. However, the difference in the marking of Curacao XT and Pitcairn XT crystals confirms that AMD has done some work on silicon, but Tahiti XTL cannot be distinguished from XT, since both crystals are absolutely clean (in a different form, Tahiti did not come across to us at all). on one video card).

Bonaire (Radeon HD 7790)

Bonaire XTX (Radeon R7 260X)

Pitcairn XT (Radeon HD 7870 GHz Editon)

Curacao XT (Radeon R9 270X)

Tahiti XT (Radeon HD 7970 GHz Editon)

Tahiti XTL (Radeon R9 280X)

Accordingly, all three video cards have direct counterparts in the «seven thousandth» series. Radeon R7 260X — HD 7790, Radeon R9 270X — HD 7870 GHz Edition, R9 280X — HD 7970 GHz Edition. Let’s consider them in more detail.

⇡#

Radeon R7 260X Specifications, Price

Like the Bonaire chip in the Radeon HD 7790, the Bonaire XTX in the R7 260X is a fully enabled GPU with 896 stream processors, 56 texture units and 16 ROPs. The processor communicates with the frame buffer via a 128-bit bus. But, in addition to TrueAudio support and updated PowerTune, the R7 260X is characterized by significantly increased clock frequencies: 1100 and 6500 MHz (core and memory, respectively) versus 1000 and 6000 MHz for the HD 7790. However, along the way, TDP increased: from 85 to 115 watts.

The specification calls for 2 GB of GDDR5 memory, while the Radeon HD 7790 officially exists in a 1 GB framebuffer version.

The

Radeon R7 260X has an MSRP of $139 for the US market. This is noticeably more than the HD 7790 (lower $107) and GeForce GTX 650 Ti ($104), while the HD 7850 and GTX 650 Ti BOOST are slightly more expensive ($149).

Note: since Russian prices for the new series have not yet been announced, American offers from the Newegg.com website are taken for comparison.

Radeon R9 270X: specs, price

GPU codenamed Curacao XT is identical to the Pitcairn XT underlying the Radeon HD 7870 GHz Edition in terms of compute units: 1280 stream processors, 80 texture units , 32 ROP, 256-bit memory bus.

Like the Radeon R7 260X, the video card is overclocked compared to its prototype: from 1000/4800 MHz (GPU/memory) to 1050/5600 MHz. But since the increase in GPU frequency is small, TDP only changed by 5W: from 175 to 180.

US MSRP for the R9 270X is $199. That’s a little more than the HD 7870 ($169) and quite comparable to the cheaper versions of the HD 7950 w/Boost ($209) and the GeForce GTX 660 ($194).

⇡#

Radeon R9 270X: design

The R9 270X reference sample is equipped with AMD’s usual radial-type cooler («turbine»), only the cooling system casing this time is more unusual and extravagant in appearance.

AMD Radeon R7 270X

AMD Radeon R7 270X

Under the shroud is a rather impressive copper-based GPU heatsink with three heatpipes, complemented by a massive frame that removes heat from the memory chips.

As usual, it’s pointless to discuss the consumer qualities of a reference design (especially in this case, when all end manufacturers already have a replacement since the «seven thousandth» series), and yet the video card is quite noticeably noisy under load, and at maximum speed The «turbine» is fantastically noisy. Fortunately, it can only be brought into this mode manually.

Radeon R9 280X: specifications, price

Of all the three cards presented, the Radeon HD 7970 GHz Edition has undergone the least changes, becoming the Radeon R9 280X. The Tahiti XTL chip still contains 2048 workable stream processors, 128 texture units and 32 ROPs, a 384-bit memory interface.

Even the frequencies have not changed at all: 1000 MHz for the GPU and 6 GHz for the video memory. From the information provided by AMD, it is not clear whether the R9 280X has an add-on for the PowerTune step ladder called Boost State, but judging by the fact that the sample issued for testing reports a core frequency of 1050 MHz, Boost has not gone anywhere.

No wonder the TDP is still an impressive 250W.

The R9 280X is priced at $299, which is really aggressive positioning, because even in the US the Radeon HD 79The 70 GHz Edition is hard to find for less than $329, with a more typical price of $389. In general, the HD 7970 marked GHz Edition has always been much more expensive than the base version of this card. Close to the R9 280X price range is the GeForce GTX 670 ($280). The GeForce GTX 770 is much more expensive ($399), while the GTX 760 is more affordable ($249).

Radeon R9 280X: Design

The Radeon R9 280X is represented by a graphics card manufactured by SAPPHIRE. Unlike reference design HD 7970 GHz Edition adapters, this card has a reinforced PCB and cooling system.

Massive open-type cooler is served by two fans with 90 mm impellers. The back surface of the board is protected by a metal plate.

Lower GPU voltage of Radeon R9270X / HD7870 (downvolting/undervolting of any GCN 1.0 cards)

The Radeon HD 7870/7850 and R9 270/270X series video cards have been out of the mining pool for quite some time and now most of the marketplaces are literally inundated with an extensive assortment of old devices based on the Pitcairn GPU and his twin brother Curacao.

Specifically, in my case, we are dealing with an XFX Radeon R9 270X (R9-270X-CDFC) video card. However, this method is suitable for both regular (reference) R9 video cards270, 270X, 280, 280X, and older Radeon HD 7870/7850 and HD 7970/7950.

Let’s take a look at the temperatures and power consumption of the card when using the native, unmodified BIOS: video memory consumption of the card is ~140 watts). The GPU warmed up to 72 degrees at 76% fan speed. In addition, as you can see in the above screenshot, the input voltage of 12 volts dipped quite noticeably and was equal to 11.50 volts: a 350-watt power supply is not able to adequately function with such a relatively voracious video card.

This, by the way, is one of the main reasons for which I undertook to undervolt this graphics adapter. It must work adequately on a 350-watt power supply, which means it must enter the limits of 11.70 volts. But, this is my personal need. For you, my guide will allow you to extend the life of the video card, and, just as important, reduce its noise, as well as power consumption.

We’re done with the introduction, now let’s start lowering the GPU voltage:

To do this, we need the BIOS editor for Radeon GCN 1.0 generation video cards « VBE7 «. This program can be downloaded from the TechPowerUp forum.

In addition, GPU-z and MSI Afterburner must be installed. The first one will allow you to find out the current voltage of the GPU, and the second one will allow you to edit the frequency of the GPU in real time, and, VERY IMPORTANT, monitor the temperature of the video card.

WHAT YOU WILL DO WITH YOUR VIDEO CARD, YOU DO ONLY AT YOUR OWN RISK! NEITHER THE AUTHOR OF THIS MATERIAL NOR THE UmTale Lab RESOURCE IS RESPONSIBLE FOR YOUR PROPERTY!

First, run the GPU-z information program and (safely) save the stock bios using the button indicated by the arrow in the screenshot below:

!) the resulting file to any folder and run the VBE7 editor.

Using the «Open» button, open the copied file and make sure that on the same first tab of the program, opposite «VRM» you have one of the following controllers CHL822x, CHL8214, UP1637, UP1801, ST6788A, or VT1556M.

In my case it is CHL822x. If your controller is not in the list, then you will not be able to set the exact voltage, and you will have to be content with just a drop-down voltage table. Which, in general, is also not particularly bad, but the field for maneuver is greatly narrowed.

Now go to the “Power Play” tab and MANDATORY edit the bottom two (in the case of HD 7000 video cards one, #3) positions #3 and #0 (position #0 is the turbo boost frequency that appeared in the R9 line):

Positions #0 and #3 must match exactly.

It all depends on your preferences: you can select the stock frequency value (line Core Clock ) and select the voltage for it (line VDDC ) (then it is better not to lower the voltage below 1.1 volts), or you can select a specific voltage (then it is better not to lower it below 0.900 volts) and select the frequency for it (in this case, it is better to seriously lower the frequency to 700-900 MHz and start from it).

Personally, I chose the second option and set exactly 1000 millivolts (1 volt VDDC), as well as the minimum safe voltage for this 900MHz (Core Clock), after which I clicked on the “ Save ” button and saved the new firmware to a separate file:

Next, I launched the ATI ATIFlash (AMD VBFlash) BIOS flashing program, loaded it using the “ Load Image” button «The bios file I just made:

And flashed it onto the card using the button» Program «:

If everything went well, the program will ask you to reboot for the changes to take effect. If it gives an error with the inscription «Fail!» — just press the «Program» button again.

Next, I moved on to testing in the stress test for FurMark video cards: Increasing the chip frequency in MSI Afteburner by ~15MHz every 5 minutes (sighting time), I found that at a voltage of 1000mV my GPU is able to operate stably at a frequency of 950MHz:

Under The load sags quite significantly: the 1000mV I set turned into 959mV. This is a normal phenomenon, you should not worry.

At 1000 MHz, FurMark instantly hung tightly, which obviously indicated a lack of supply voltage. Therefore, I decided to slightly raise the voltage to 1.05 volts.

As a result, the video card was able to work stably for 38 minutes in a “donut”, after which I was sure that the further test would simply not bring any surprises:

cooling system. In parallel, GPU power consumption dropped from 94 watts to 62 watts! In my opinion, only because of this it is worth carrying out the undervolting procedure.

In addition to FurMark, I used The Witcher 2/3 and Destiny 2 running at 2560×1440 as a heavy 3D workload. XFX R9The 270X with the modified bios handled every game without any problems.

I would like to note that in the same Witcher the temperature did not exceed 53 degrees, which is 8 degrees lower than in the donut. Accordingly, the power consumption of the video card will also be slightly lower than in the stress test.
